Abstract: Cesarean scar pregnancy (CSP) is a special type of ectopic pregnancy that occurs after a cesarean section. In recent years, with an increase in the cesarean section rate, the incidence of cesarean scar pregnancies has also increased. This article systematically reviews the development and latest progress of various CSP classification methods to compare the diagnosis and treatment strategies of different CSP classifications and better manage patients with CSP. We evaluated various classification methods using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2011 level of evidence, providing a basis for objective and precise classification of CSP in the future and thus providing more accurate clinical guidance for individualized treatment. Keywords: cesarean scar pregnancy, classification, treatment
